Annual USSF Registration – Referees need to be registered with the US Soccer Federation in order to officiate games for Mustang. The registration year runs from July 1 through June 30. For example, to receive your 2020 badge, you must submit your renewal between July1, 2019 and June 30, 2020. The US Soccer Federation does NOT send reminders to renew your registration, and if you fail to renew you could be required to take a recertification class before you can renew, so do not let it lapse! All Grassroots referees are strongly urged to renew using the online system. For more details, including access to the online system, click HERE to go to the CNRA site.
